What an agent can do for a plumber

The hardest thing about selling software to a trade business is that the owner is under a sink when you call. That is also the whole opportunity. The work that pays is on site. Everything else — the phone, the quote, the reminder, the invoice chase — happens in the gaps, badly, at 9pm.

So start there. Not with what an agent could theoretically do, but with where the day actually leaks.

The day

A two-van plumbing business gets somewhere between a handful and a few dozen inbound contacts a day: calls, texts, a form on the website, a message on a local trades listing. Most are one of four things. Can you come out? How much is it? When are you coming? Where is my invoice?

The owner answers what they can between jobs. Voicemail takes the rest. Some of those callers ring the next plumber on the list before the owner gets back to the van. That is the loss, and it is invisible — you never see the job you didn’t get.

Evenings are for the office work: writing up quotes from photos and scribbles, sending invoices, chasing the two that are three weeks overdue, and moving tomorrow around because a job overran.

What the agent takes

An agent is a good fit for work that is high-volume, low-variance, and needs to happen immediately. In a trade business that is:

Answering. Every call and message gets picked up on the first ring, at 7am and at 10pm. The agent knows the service area, the trades covered, the callout fee structure, and the difference between “no hot water” and “water coming through the ceiling.”

Triage and booking. It asks the three or four questions that decide the job — what is happening, how long has it been happening, is water still running, what is the address — and then offers real slots from the real calendar. Not “someone will call you back.” An actual time, written into the actual diary, with the job notes attached.

Reminders and confirmations. The day-before text. The “van is 20 minutes out” message. The nudge on a quote that has been sitting unread for five days. This is the cheapest revenue in any trade business and nobody has time to do it consistently.

The paper trail. Quote from a template with the job details already filled in. Invoice after the job is marked done. The polite second and third reminder on an overdue one.

None of that is clever. All of it is relentless, which is the part a person can’t be.

What stays human

The agent should be built with a short list of things it does not do, and it should be a real list, not a disclaimer.

It does not price a job it hasn’t seen. It can give the published callout fee and an indicative range for standard work; anything with a variable in it goes to the owner as a note, not to the customer as a number.

It does not handle an emergency alone. Burst pipe, gas smell, no heat with a baby in the house — the agent’s job is to recognise it in the first ten seconds, say something reassuring and useful, and get a human on the line.

It does not argue. An unhappy customer, a dispute over an invoice, anything with heat in it: hand off, immediately, with the whole conversation attached so the owner doesn’t have to ask the customer to repeat themselves.

It does not decide who to prioritise when the day is full. It shows the conflict and lets the owner call it.

Why the handoff has to be good

Everything above depends on one design decision: the agent knows when it is out of its depth, and getting out of its depth is a normal outcome rather than a failure. A front-desk agent that hands off cleanly ten times a day is doing its job. One that improvises to avoid handing off is a liability wearing your business’s name.

The handoff needs to carry context — who called, what they said, what the agent already promised — and it needs a place to land: a text, a task, a line in the inbox the owner already reads. If the handoff lands somewhere nobody looks, the agent has made things worse.

What it is worth

We don’t lead with a percentage, because the honest answer depends on how much is being missed today. The measurable things are: calls answered outside working hours, quotes that got a follow-up, invoices paid inside terms, and evenings not spent doing admin.

The first one usually pays for the build. The last one is why people actually do it.
